BACKGROUND AND OBJECTIVES: The Oriental herbal materials known as aconitine have long been used in oriental traditional medicine for their analgesic and antiinflammatory effects. Aconitine and its related alkaloids are known cardiotoxins with no therapeutic role in modern western medicine. We have studied the cardiovascular side effects of intoxication that took place in otherwise healthy individuals after ingestion of herbal decoctions containing aconite alkaloids. MATERIALS AND METHOD: During a six-year interval from 1990 to 1996, 9 cases of accidental herb-induced aconitine intoxication were managed in Kyung Hee university medical center. Hospital records were reviewed in detail. RESULTS: All patients developed symptoms of aconitine toxicity within 4 hours of herb ingestion. The frequency of the order in cardinal symptoms of acute aconitine poisoning was nausea or vomiting, irritability, chest discomfort, dizziness, etc. Nine patients developed arrhythmias, including multifocal APC with aberrancy, multifocal VPC, ventricular tachycardia, etc. Administration of isotonic saline, dopamine, atropine and lidocaine with supportive cares brought clinical recovery and disappearance of arrhythmias in most cases within several hours. However, one case of acute aconitine poisoning had been dead of cardiac arrest due to ventricular fibrillation. CONCLUSION: Aconitine and its related alkaloids can cause toxic effects and even fatal poisoning. These cases point to the need for strict surveillance of herbal substances with low safety margins.

BACKGROUND: The purpose of this study is to define the risk factors of S. epidermidis acquisition and the epidemiology of strain variation in acute leukemia patients. METHODS: The participants were 155 patients of acute leukemia admitted in a University hospital for 11 months. 83 patients are the isolated group who had isolated S. epidermidis from body sites (blood, oral cavity, nares, rectum) and 72 patients are the not isolated group who had not isolated S. epidermidis. Isolates were analysed by CHEF and cluster analysis with dendrogram. Differences In proportions were tested with the Chi-square and Fisher's exact test. RESULTS: Ninety-one S. epidermidis were obtained from blood, oral cavity, nares, and rectum. The major proportion of positive culture was 81.3% from nares. Eight-nine S. epidermidis were isolated from healthcare workers. There were significant development of bacteremia in patients with S. epidermidis from nares. Resistance rate of S. epidermidis was 75.8% to methicillin, 86.3% to erythromycin, 81.l% to gentamicin, 68.9% to ciprofloxacin, 0% on vancomycin. There was significant difference on resistance rate between patients and healthcare workers' group. There was no relation between the strain of patients and those of healthcare workers. Sex age, diagnosis, length of stay, type of chemotherapy, duration of chemotherapy, Type of central venous catheter. duration of central venous catheter, prior antibiotic therapy, number of antibiotics, site of nosocomial infection, neutropenic period were not significantly different between S. epidermidis isolated group and not isolated group. Significant risk factors included duration of central venous catheter. hyper-alimentation, and folliculitis. CONCLUSION: Our result suggests that S. epidermidis in nares can be a risk factor of bacteremia. This research would be helpful for decreasing the S. epidermidis of immunocompromised patients.

Chusid et al proposed diagnostic criteria of hypereosinophilic syndrome (HES) that remain valid today. These were, (1) a sustained peripheral blood eosinophil count of more than 1500/L present for longer than 6 months ; (2) no evidence of other apparent causes for eosinophilia, and (3) presumptive signs of parenchymal organ involvement. Any organ system may be affected in HES, but the most severe clinicopathological involvements are of the heart and nervous system. Although multiple organ systems may be involved, the most common cause of morbidity and mortality is cardiac involvement with extensive fibrous thickening of the endomyocardium and overlying thrombus. We report a case of acute peri-myocarditis with eosinophilia, which was confirmed as eosinophilic myocarditis by endomyocardial biopsy, with literature review.

The myoclonic epilepsies of infancy and early childhood pose the most difficult problems in the diagnosis and classification of epilepsies because they are often confused with the Lennox-Gastaut syndrome sharing a number of common features. However, their correct differentiation is easily justifiable because some of the myoclonic epilepsies of early childhood have better prognosis than the Lennox-Gastaut syndrome. We experienced and treated a 4-year-old boy who had normal intellectual function but frequent myoclonic and generalized clinic-tonic-clinic seizures, which were successfully controlled by anti-epileptic drugs. Hence we report a case with brief review of literatures.

Purpose: Benign prostatic hyperplasia (BPH) is associated with lower urinary tract symptoms and negatively affects the quality of life. We aimed to investigate the treatment pattern of BPH in South Korea. Methods: Information on treatment modalities and diagnoses of BPH was obtained from the Health Insurance Review and Assessment Service-Aged Patient Sample. Data on BPH patients aged ≥60 years from 2012 to 2016 were obtained. We surveyed the treatment pattern of BPH, including the types of drugs used and surgeries performed, according to the type of institution. Results: In this study, 18,260–24,657 BPH patients treated between 2012 and 2016 were included. The number of patients showed an increasing pattern, and drug therapy was the major treatment method used for BPH (98.77%). Moreover, the pattern of increased pharmacotherapy use for BPH was reinforced by the increasing number of patients. Prescription of α-blockers only was dominant in this cohort (45.7%). Transurethral resection of the prostate (TURP) was the most commonly used surgical treatment for BPH (53.6%), but it showed a decreasing pattern over time. In contrast, holmium laser enucleation of the prostate (HoLEP) showed an increase from 19.4% to 39.7%. Conclusions The most common treatment for BPH was drug therapy, predominantly only α-blocker therapy. The surgical treatment trend has changed from TURP to HoLEP.

OBJECTIVE: The purpose of this study is to determine the efficacy of anterior lumbar interbody fusion(ALIF) for the patients with focal type of degenerative flat back. METHODS: The authors reviewed clinical and radiologic data of 16 patients with focal type of degenerative flat back who underwent ALIF during the period between December 1999 and November 2000. The operation procedure was ALIF using titanium or carbon fiber cages of lordotic angle, which were filled with allograft or autograft mixed with allograft through minilaparotomy. RESULTS: The majority of the patients were female(15 female: 1 male) and the mean age was 60.1 years. Six patients were operated on one level, ten on two levels. The mean follow up period was 10.7 months. The mean operation time was 131minutes and the average estimated blood loss was 133ml. Transfusion was not needed in any case. The mean preoperative lumbar lordotic angle was 4.1 degree(-7.4-41.6) and improved to 17.5 degree(-4.5-41.9) postoperatively. Radiological fusion was achieved in 13 patients(81%). The Oswestry disability index score improved from 62.5% to 23.9% and the patient's subjective improvement rate was 80%. Complications were infection in one patient, incisional hernia in one, symptomatic pseudoarthrosis in one and transient sympathetic disturbance in left leg in three. CONCLUSION: In a subset of the patients with degenerative flat back who showed disc degeneration in one or two levels, ALIF using cages improved patient's symptoms effectively. It seems that ALIF through minilaparotomy can be one of the surgical options in the treatment of the focal type of degenerative flat back.

PURPOSE: This study was performed to investigate the growth pattern of epileptic children on medication with anticonvulsants. METHODS: We measured the weight, height and head circumference of 219 epileptic children on medication with anticonvulsants through the review of the medical records, compared these with those of the control group as means of Standard Measurement of Body Growth for Korean Chidren and Adolescence reformed at 1998 and analyzed this data according to sex, age at the start of medication, duration of medication, the cause of epilepsy, the type of seizure and the number of anticonvulsants. RESULTS: The weight and height at the start of medication with anticonvulsants had no difference from those of the control group according to sex, age at the start of medication, the cause of epilepsy, the type of seizure and the number of anticonvulsants, but the head circumference at the start of medication was smaller than that of the control group(P<0.05), especially in children aged 1 to 6 years(P<0.005) and in children with symptomatic epilepsy(P<0.001). The increase of weight, height and head circumference had no difference from those of the control group according to sex, age, duration of medication, the cause of epilepsy, the type of seizure and the number of anticonvulsants. CONCLUSION: The increase of weight, height and head circumference of epileptic children on medication with anticonvulsants had no difference from those of normal children.

OBJECTIVE: Attention-deficit hyperactivity disorder is a highly heritable psychiatric condition of early childhood onset characterized by marked inattention, hyperactivity and impulsiveness. Genes involved in catecholamine pathways, including catechol-O-methyltransferase (COMT), represent potential candidates, given that around 70% of children with ADHD show a symptomatic improvement when treated with methylphenidate, a psychostimulant. This study was designed to investigate the association of COMT polymorphism with ADHD in Korean population. METHOD: In this study, we used both family-based (the haplotype relative risk & the haplotype-based haplotype relative risk design) and case-control approaches to examine COMT polymorphism. The sample included 31 Korean children (25 males, 6 females) diagnosed as ADHD by DSM-IV, their 31 families with 31 mothers and 27 fathers and 106 normal controls. RESULTS: There were no differences of COMT genotype and allele frequencies between ADHD patients and control subjects. Also, there was no difference of COMT genotype between ADHD patients and HRR controls. The COMT1 allele frequencies of normal control group in Korean population (75%) was significantly different with that frequency of Caucasian population (50%). CONCLUSION: These results suggest that COMT polymorphism is not associated with ADHD in Korean population. However, the possibility of interacting effects of COMT with other genes or environment should be investigated.
